This is Weistec's trunk mounted water tank upgrade that applies to supercharged M156 vehicles as well as M113 Kompressor vehicles such as the W211 E55 AMG. This will allow one to better cool their supercharged vehicle and assist with the issue of heat soak that affects positive displacement supercharged cars that are making back to back wide open throttle runs. One can put ice in the reservoir to further help cool air charge temperature entering the intake path. Hot water can easily be drained with the drain system.

Key Features:

Precision TIG Welded Aluminum
Large mouth fill port for simple addition of ice
Complete system will contain approximately 6 US Gallons
2000 G.P.H. Internal bulge pump for added flow and consistency
Aerospace grade fittings, wiring, and lines are included for easy installation on Weistec and factory Supercharger systems.
